AttributeError: 'Worksheet' object has no attribute 'set_column'

I am getting an error that seems... wrong. Because of course worksheet object has set_column() as a function, it's in the docs. I've probably done something dumb like drop a parenthesis.

Here's the error:

Traceback (most recent call last):
  File "scrubaddresses.py", line 137, in <module>
    run()
  File "scrubaddresses.py", line 118, in run
    format_col_width(worksheet)
  File "scrubaddresses.py", line 24, in auto_format_cell_width
    ws.set_column('B:C', 20)
AttributeError: 'Worksheet' object has no attribute 'set_column'

Here's my ridiculous import. Config is some constants, controller has some helper functions.

from smartystreets_python_sdk import StaticCredentials, exceptions, Batch, ClientBuilder
from smartystreets_python_sdk.us_street import Lookup as StreetLookup
from pathlib import Path
import pandas as pd
import numpy as np
import config
from controller import getExcel, clean

The func in question:

def format_col_width(ws):
    ws.set_column('B:C', 20)
    ws.set_column('D', 1)
    ws.set_column('E', 20)

Where the ws being passed comes from:

            df1 = df.replace(np.nan, '', regex=True)
            print(df1)

            df1.to_excel(writer, sheet, index = False, engine='xlsxwriter')
            worksheet = writer.sheets[sheet]
            format_col_width(worksheet)

Did I forget to import something? Xlsxwriter is installed.

There is an error in the single column ranges. They should be D:D instead of D since the method needs a start and end column even if they are the same.

With that modification the code should work:

import pandas as pd

def format_col_width(ws):
    ws.set_column('B:C', 20)
    ws.set_column('D:D', 1)
    ws.set_column('E:E', 20)

df = pd.DataFrame({'Data1': [10, 20, 30, 20, 15, 30, 45]})

writer = pd.ExcelWriter('pandas_test.xlsx', engine='xlsxwriter')
df.to_excel(writer, sheet_name='Sheet1')

workbook  = writer.book
worksheet = writer.sheets['Sheet1']

format_col_width(worksheet)

writer.save()

Output: enter image description here

Try the above code and see if it works. If it doesn't then XlsxWriter may not be installed and Pandas is defaulting to OpenPyXL.

I had the same problem, the following worked for me:

def format_col_width(ws):
    ws.column_dimensions['B'].width = 20
    ws.column_dimensions['C'].width = 20
    ws.column_dimensions['D'].width = 1
    ws.column_dimensions['E'].width = 20

The reason it gives: AttributeError: 'Worksheet' object has no attribute 'write'

This is because you have not installed xlsxwriter on your PC.

you can use:

pip install xlsxwriter

and it will work isa.
